    • Laser Safety Interlock Shutter

    specifically designed for highpower continuouswave (CW) lasers and highenergy pulsed laser systems. Featuring a highspeed electromechanical drive structure and highdamagethreshold mirrors, it provides reliable, fast, and stable beam control in applications such as laser safety interlocking, pulse gating, and laser exposure control. The MPLST300 supports a large 16 mm clear aperture and handles up to 300 W of continuous optical power. It offers both metallic and dielectric mirror options, making it compatible with Nd:YAG, CO₂, UV, and other laser systems.

    Product features：Large aperture design; supports high-energy lasers; supports laser safety interlocking; compatible with metal and dielectric mirrors

    Part Number：MP-LST-300

    Application area：Laser safety interlock systems | Q-switched laser pulse gating | Nd:YAG solid-state lasers | High-power | industrial lasers | Semiconductor manufacturing | Scientific research platforms | Optical testing and metrology | Laser material processing
